tened thereto, in cross brace fashion, a longitudinal member in the form of a round bar 39, which 7 at its front end pivotally carries a bracket or arm 40, in turn pivotally carrying a bracket or arm 4|. These arms 40, 41 constitute a bracket for carrying a transverse reel shaft 42, on which is rotatably supported the harvester reel 43, the

A reel being drivenin any way, as for example by the chains and sprocket wheels shown. The arm 40 carries a plate 44, in which is pivotally connected a longitudinal rod 45 having connection with a spring 46 anchored at 41 to the bar 39', as shown in Figure 2.

The rear end of the brace bar 39 extends a distance rearwardly of the elevator 21, to carry a pair of toothed quadrants 48, (see also Figure 2) and a pair of hand levers 49; 50. The lever 49- has connected to it a forwardly extendingrod 5|, which has its front end connected to the plate 44'on the arm 40. Similarly, the lever 53 has connected to it a forked link 52, the front ends of which are connected at spaced points to the reel bracket part 4!. By means of the lever .49 and rod 5|, the arm 4!] can be actuated to raise or lower the reel shaft 42 and reel 43; while, by means of the lever and link 52, the arm 4| can be actuated to move the reel fore and aft. The levers just described have the usual detents associated with them and .cooperable with the quadrants 48 to hold the levers and associated partslocked in adjusted positions. The spring 46 serves to counterbalance the weight of the reel as it is adjustably moved by said levers. It is to be noted that the rearward extension of the. bar 39 serves to locate the. levers 49, 50 in a position accessible to the operator on his station 29. The bar 39' further performs the important additional function of cross-bracing the sides 2! of the elevator. .Thus, a lighter structure for the elevator may be utilized.

These levers 49, Stare mounted on the elevator 21 through the medium of the bar 39' and the same is true of the reel 43. Thus, as the harvester part comprising the platform 20 and elevator 2'! are adjusted up and down by the adjusting rack bar 36, the reel adjusting means moves bodily with the elevator and the relative positions of these parts consequently are never altered. Regardless of the elevation of the harvesterpart, the reel control levers always remain accessible to the operator on his platform 29.

From the above description, it can now be seen that an improved elevator construction, and reel mounting and adjusting means have been pro vided for harvester threshers.

2. In a harvester thresher, a longitudinal thresher having a feeder housing forwardly thereof, a transverse harvester platform associated with the thresher for up and down movement, an elevator rigidly mounted on the stubbleward end of the platform and discharging into said feeder housing, said elevator carrying a longitudinal bar thereacross, a reel carried on the forward end of said bar for up and down and fore and aft movement, said bar being extended rearwardly of the elevator, an operators platform carried by the grainward side of the thresher, and lever mechanism on the rearwardly extended end of the bar accessible from the operators platform for adjusting the reel.

3. A harvester thresher comprising a thresher, a harvester platform including an elevator rigidly carried by the platform, a reel carried by the elevator, means carried by the elevator for adjusting the reel, and means for adjusting the platform and elevator as a unit.

4. A harvester comprising a longitudinal thresher, a harvester platform including an elevator rigidly carried thereby, an operators platform at the grainward side of the thresher, a support on the elevator, a reel adjustably carried on the support, means on the support to adjust the reel, and means to adjust the platform to alter the height of out, said reel and platform adjusting means being operable from the operators platform.

5. In a harvester thresher, a thresher having a feeder housing, a transverse harvester platform associated with the thresher for up and down adjustment, an elevator carried at the stubbleward end of the platform and feeding into the feeder housing, a longitudinal member carried across said elevator, a reel adjustably carried at the forward end of said member, means on the member including levers for adjusting said reel, and means on said member to counterbalance the weight of said reel.

6. In a harvester thresher, a thresher having a feeder housing, a transverse harvester platform associated with the thresher for up and down adjustment, an elevator carried at the stubbleward end of the platform and feeding into the feeder housing, a longitudinal member carried across said elevator, means to adjust the harvester platform up and down, and a reel and adjusting means therefor carried on said member, said elevator, member, and reel adjusting means moving bodily with the platform when it is adjusted.
